you just did:-)

Rui,
acpi_video_bus_get_one_device() is returning -errno style status,
but acpi_video_bus_get_devices() is expecting an ACPICA style status

                status = acpi_video_bus_get_one_device(dev, video);
                if (ACPI_FAILURE(status)) {
                        ACPI_EXCEPTION((AE_INFO, status, "Cant attach device"));
                        continue;
                }

looks like this was true in 2.6.23 as well...

-Len
